According to the nonprofit shark research group Ocearch, the 2,300-pound shark they've named Katharine surfaced Saturday morning in the Atlantic off Edgewater in Volusia County.

The group has been tracking Katharine since August, when the shark was tagged off Cape Cod, Mass. Researchers tell Florida Today that thanks to Katharine, they're learning that great white sharks swim south much faster than previously thought.

Great white sharks migrate south in the late fall and early winter.

Ocearch researchers capture, tag and release great whites to help gather more data about the large predators. Off-shore transmitters help researchers track the sharks by satellite.
